摘要
通过研究4种煅烧温度对Pb(Zr0.52Ti0.48)O3(PZT)粉体粒径分布及晶体结构、陶瓷片微观形貌及压电性能的影响确定PZT最优合成条件。结合超声分散技术制备PZT/温石棉纤维/水泥材料(PZTCC),并分别测试复合粉体晶体结构及经压制极化后PZTCC复合片的压电性能。800℃时PZT钙钛矿特征最明显,晶粒饱满;相应PZT陶瓷片、PZTCC复合片均具有较高压电性能,其压电常数d33分别达119.2pC/N、32.5pC/N。
The optimum synthesis condition of PZT nanopowder was determined through characterizing effect of4 calcination temperatures on its particle size distribution,crystal structure,microstructure,and piezoelectric properties of PZT ceramics.The PZT/chrysotile fiber/cement composites（PZTCC）were prepared combining with the ultrasonic dispersing technology,and the cystal structures of the mixed powder and the piezoelectric properties of the PZTCC wafer after pressing polarization were measured,respectively.The results show that PZT has the best perovskite cystal structure and plump crystalline grain at the calcinated temperature of 800℃,and the corresponding PZT ceramic,PZTCC wafer have relatively high piezoelectric coefficient d33 of 119.2pC/N,32.5pC/N respectively.
